Rails: Log stuff to rails app logs from any ruby class

Question

I want to be able to log things to my Rail's app logs from a ruby class.

I was hoping to do logger.info "some stuff" from a class in my_app/app/myClass.rb, but it's not defined. When I use logger in my controllers and elsewhere it works.

I'm a bit new to Rails / Ruby, and I'm assuming this is simply because the logger class isn't included in myClass.rb, but it is automatically included in all controllers, models, etc.

How can I include the logger class in an arbitrary ruby class, or otherwise log to my rails app from a ruby class?

(Added tag for "Pundit" since specifically I am using logger in a Pundit policy file, but it's just a ruby class :P)

Answer 1

If you want to create your own logger:

class MyClass
  def initialize
     @app_logger = Logger.new("#{Rails.root}/log/app.log")
  end

  def othermethod
     @app_logger.info("anything here")
  end 
end 

Answer 2

You can load the app's logger into a method on Object during the rails app initialization process

# config/initializers/my_logger.rb

class Object
  def mylog
    @logger ||= Rails.logger
  end
end

Enhancing / changing the Object class should be done with care
